mini me swap for obd0 wagos

jimbix2003

ok so have searched high and low and have not gotten a straight answer so here it goes. anyone know of a good diy for obd0 mini me swap using a y8 head? do have to convert to obd1 and what do i need? i know about the head studs deal with the y8 and could i just to a dpi swat to mpfi then just ad a jumper harness and ecu and the head swap? i am finding all kinds of different stuff but not the right answers. so any help for you guys would be great thanks.

IMO a mini swap with a y8 head is too much of a PITA the cam angle is off so u have to have an adjustable cam gear just to put it at the right setting then your limited to certain deistributors. if u use z6 head its a lot simpler i have a spare one for sale actually since i picker up a z6 long block last night im gunna build it for my wagon.

anywho im not saying its impossible but the reason your not finding info on it is becasue people tend to stay away from y8 mini me swaps.

so you are saying just do the z6 head swap and it stays obd0 or does it move it to obd1? and from dpi to mpfi ? basically i want multi point and little more power w/ vtec and gas milage

the y8/z6 intake is also going to make things alot harder for you. instead of using the y8/z6 intake(it's OBD1), use one from a D16A6 or similar engine because its OBD0.

so do you know of a list of things i need and how to do it? i am looking for a little guidance on this

Z6 is OBD-1 and MPFI along with VTEC.

VTEC crossover is almost unnoticeable but it's pretty peppy for a SOHC.

You'll need to wire MPFI and VTEC, need intake manifold, complete head, Si throttle cable, and a bunch of random stuff you'll come across.

I've got a 4WD and will be doing a minime or might just throw the whole Z6 long bloack in.
I'll be running the engine on OBD0 at first either with the PM6 ECU (with one wire vtec mod) or more likely the PW0 B16A1 ECU as I've got more experience tuning those ones.

Makes no difference what ECU you choose so long as you can tune it well.
VTEC cross over should be smooth as glass if it's in the right place.

so i found a po8-1 head is that the head i wanna use?

i say convert to obd1 while you're at it since it'll put you where you wanna be if you ever do any serious mods. at the same time, why cheap out on the bottom end? d16z6 are a dime a dozen.

jimbix2003

i dont know ? bcause thats the block thats in there you think it would be more benificial to just do a whole z6 swap ? what about the wiring just use the p28? oh and what about the head # po8-1? is that the z6 head?

ThinkFab

its from the 92 VTi D15B Auto

So I guess it's bad that my car starts spinning when VTEC crosses over? Mine engages from hell. Strong as all get out..

naww, thats for SOHC only (i think, at least i could never tell when it kicks in in my friends D17 on his '02 Civic EX). also newer VTEC engines are kinda "lame", like the new K20Z3 its quiet.

BUT...as for the B-series... my B16A sure as hell didnt engage smoothly, it made my car hella loud and took off as if someone pinched its ass.

I dont see why it wouldn't be more benificial. It all makes more sense to me to go with the Z6 long block since you'll have the ecu for it, .1L more, and a VTEC head designed to work with the bottom end. i've seen Z6 long blocks sold locally anywhere from $75-$300. When it comes to cars, if money will allow it, keep it as simple as possible!

an obd0 Si dizzy will bolt right onto a z6 head right? i have everything to do a mini me swap and then some i should do it besides im leaking a ton of oil from my headgasket and im sure all the boost this summer wasnt too good for it.

Depends on your cams.
However, with a stock B16 the VTEC kick is there as some sort of marketting gimmick so you get the illusion that all hell broke lose. If you actually lower it then it makes more power.
The kick happens because the torque is dropping off the low cam and comes in with a vengence on the high cam as it was already capable of making more torque before you asked for it's help so it climbs a torque cliff if you like.
Ideal location is where the torque curve for the low cam and high cam cross.

Normally stick a B16 on the dyno and set VTEC way up high and do the low cam map, then stick it quite low and do the high cam map.
Put the two plots on top of each other, where the torque curve crosses is the ideal VTEC point. It's never as high as stock.

Certainly tho some crazier cams you will get a "kick" from, but the setup should be much the same. Tyre spinning isn't ideal right ?

obd0 si dizzy bolts up to the y8 head no prob. the z6 only gets 2 bolts in.

hey will this diy work for z6 swap if a mpfi swap is done as well?
